The most noteworthy thing on E Grand is Navy Pier. Mostly a tourist trap, Navy Pier is chock full of random attractions from a Ferris Wheel to a trolley (bus) that runs from the parking lot to the end of the pier. One thing that is worth seeing is the fireworks show every weekend in the summer. There is expo space that is used for things like the flower show and a concert stage that does host some big names from time to time. If you vist Navy Pier for a specific event, you'll probably enjoy it, but if you expect it to be an event in itself you'll just end up wasting money.
